Creating forming tools is too simple now. Build a model that
looks like the forming tool die. Open one of the samples given to
see what it should look like. Save the model in your \design
library\forming tools\subfolder name folder. Click on the forming
tool icon in your sheetmetal toolbar. In the property manager click
in the stopping face selection box and then select the stopping
face in the graphics area. If your forming tool is going to create
openings in your sheetmetal part, then you will need to click in
the Faces to Remove selection box of the property manager and then
select the faces on the model that will create the hole. Click the
Ok button and save the model again.

You now have a forming tool that you can use. You use to have to do
most of this work manually.You would create a base extrude. Create
the forming tool features. Then cut away the base feature. You
would manually create your orientation sketch and color faces to
remove red.
